"A player is allowed to replace an unintended call if the conditions described in Law 25A are met, no matter how he may become aware of his error. Footnote to Law 25A (Dec 2011)" Can the same interpretation be placed on an unintended lead? Example Declarer is running dummy's long Diamonds. He is about to lead the ten but out of his lips appear the words "ten of hearts" (which, unhappily, is also in Dummy). The gasps around the table (including from dummy) make him realise his 'slip of the tongue'. Assuming the Director is happy that the play was unintended can it be changed under 45C 4 b?
